Abstract
Timed Petri nets, a formalism developed specifically for representation of concurrent activities, are popular models of discrete-event system. For net models which can be decomposed into simple cyclic subnets, the performance can be determined on the basis of components, without the exhaustive analysis of the behavior of the whole system; such an approach is known as structural analysis. The paper overviews the formal basic concepts of structural methods and uses manufacturing cells as an illustration of structural analysis.
